Fluorescent light is used to image the bud of a cannabis plant. The trichomes on the bud of a cannabis (Cannabis sativa) plant are full of Tetrahydrocannabinol (THC)and glow green. The chlorophyll filled cells of the leaf glow red. The width of the green trichome heads is 90 um, or about the width of a human hair. This is an example of a plant that is past harvest time as the THC laden trichome heads have started to shrivel.
